Description

Technical Field

[0001] The invention belongs to the technical field of coal mine tunnel dust removal, and in particular provides a coal mine safe production tunnel dust removal device. Background Art

[0002] When the coal seam is very close to the surface, it is generally chosen to directly strip off the surface soil layer to mine the coal. This is an open-pit coal mine. When the coal seam is far away from the surface, operations need to be carried out in tunnels during the production process. At this time, the tunnels need to be dusted regularly to ensure the safety of the coal mine tunnels.

[0003] For example, a coal mine safety production tunnel dust removal device with application number "202420322122.1" can achieve on-site atomization dust reduction by applying this patented equipment, but its gas-liquid treatment process is relatively independent. During the operation of the equipment, the two systems do not have good feedback interaction, and it is inevitable that power matching or mutual interference will occur. In addition, the gas after the dust removal is started is directly discharged from the bottom, which can easily cause the airflow to impact the dust that falls to the ground through water sprinkling dust removal, causing it to float in the air again and affect the dust removal effect. Summary of the Invention

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is: a coal mine safety production tunnel dust removal device, including a vehicle body and universal wheels, universal wheels are installed at the four corners of the lower end of the vehicle body, a handrail is installed on one side of the upper end of the vehicle body, a column is fixedly connected to the center of the upper part of the vehicle body, a crossbeam is fixedly connected above the column, a pneumatic dust removal component is installed above the vehicle body, and a liquid dust removal component is installed above the crossbeam.

[0005] Furthermore, the pneumatic dust removal assembly includes two double-bag dust collectors, which are connected by a connecting pipe. The air inlet pipe of the double-bag dust collector is connected to a vertical pipe through an exhaust pipe. A ball cover is fixedly connected to the top of the vertical pipe. A cover is buckled on the top of the two double-bag dust collectors, and an air pump is installed on the outer wall of the exhaust pipe of the double-bag dust collector.

[0006] Furthermore, the lower end of the vertical pipe is fixedly connected to one side of the upper end of the vehicle body, and the double-bag dust collector is fixedly connected to the other side of the upper end of the vehicle body.

[0007] Furthermore, the liquid dust removal assembly includes a water pipe, the inlet of the water pipe is connected to a water tank through a water pump, the water tank is arranged on the vehicle body below the crossbeam, the outlet of the water pipe is rotatably connected to a drainage cover through a sealed bearing, the drainage cover is arranged below one end of the crossbeam, the drainage cover is connected to gear 2, a servo motor is installed on the crossbeam, the output shaft of the servo motor is fixedly connected to gear 1, and the outer wall of gear 1 is meshed with the outer wall of gear 2.

[0008] Furthermore, the bottom of the drain cover is circular, with the middle part thereof being concave inwards, and a water retaining edge is provided on the periphery of the drain cover, the water retaining edge comprising a plurality of vertical retaining plates arranged at intervals, and the outlet of the water pipe is provided directly above the concave middle part of the drain cover.

[0009] Furthermore, the outlet of the air pump is connected to a high position or to an external air supply pipeline through a pipeline.

[0010] Furthermore, outer walls on both sides of the water pipe are fixedly connected to the crossbeam.

[0011] Furthermore, a rubber sleeve is sleeved and fixed on the outer wall of the handrail.

[0012] The beneficial effects of using the present invention are:

[0013] This solution uses intermittent water spraying to reduce dust in the air in the area. During the water spraying, the air around the dome will be continuously extracted, guiding the air to gather inward. The air passes through the water curtain to achieve dust removal. The organic combination of spraying and exhaust effectively avoids the problem of using pneumatic and liquid methods for dust removal separately. If the pneumatic and liquid methods are not combined and used separately, they are likely to cause mutual interference.

[0014] By exhausting the air upwards or connecting the exhaust end to the ventilation duct, the dust problem caused by the air flow hitting the ground is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Refer to the attached Figure 1-6 : In this embodiment, the outlet of the air pump 305 is connected to a high position or to an external air supply pipeline through a pipeline.

[0028] Working principle:

[0029] When the coal mine safety production tunnel dust removal device is needed, the user can first add water for dust removal in the water tank 404, and then push the whole structure into the coal mine tunnel where dust removal is required (the user can wear dust-proof goggles and dust masks to operate), and then start the water pump 407 and the air pump 305. The water pump 407 pressurizes the water in the water tank 404 and pumps it out to the drainage cover 403. Due to the shape of the water retaining part and the gap below the drainage cover 403 (similar to the fire sprinkler), the water in the water tank 404 is pressurized and the gap is small. ), so that the high-pressure water flow sprayed on the drainage cover 403 will be ejected in an arc-shaped divergent manner from the notch, and then the servo motor 401 drives the drainage cover 403 to rotate through the gear 1 402 and the gear 2 406, so that the water flow discharged from the drainage cover 403 appears in the form of an intermittent water curtain. At the same time, the air pump 305 can draw air from the ball cover 301, and transport the surrounding air to the double bag dust collector 302 through the vertical pipe 307 and the exhaust pipe 306, so that the air flow in the double bag dust collector The dust collector 302 flows inside to achieve dust removal, and the gas around the ball cover 301 will be continuously extracted, so that it will continue to move closer to the ball cover 301. During the process of the gas constantly moving inward, the gas will first pass through the intermittent water curtain and then be extracted, so that the surrounding airflow can better contact with the water curtain to achieve dust removal. Compared with traditional technologies, it uses pneumatic and liquid methods to remove dust separately, without combining pneumatic and liquid, and only using them separately, which easily causes the problem of mutual interference between the two. In this case, the gas around the ball cover 301 will be continuously extracted, so that it will continue to move closer to the ball cover 301. During the process of the gas constantly moving inward, the gas will first pass through the intermittent water curtain and then be extracted, so that the surrounding airflow can better contact with the water curtain to achieve dust removal, effectively avoiding the use of pneumatic and liquid methods to remove dust separately, without combining pneumatic and liquid, and only using them separately, which easily causes the problem of mutual interference between the two.

[0030] The gas purified by the double bag dust collector 302 can be directly discharged to a high position or transported to an external air supply pipeline. Compared with directly discharging the gas after the dust removal is started from the bottom, it is easy for the airflow to impact the dust that falls on the ground through water sprinkling dust removal, causing it to float in the air again and affect the dust removal effect. In this case, the gas can be directly discharged to a high position or transported to an external air supply pipeline, so that the purified gas accumulates at the top of the tunnel, and a downward airflow is generated in the tunnel, so that the unpurified air can better contact with the water curtain or be drawn into the ball cover 301, or it can be directly transported to an external air supply pipeline, which can effectively avoid directly discharging the gas after the dust removal is started from the bottom, which is easy for the airflow to impact the dust that falls on the ground through water sprinkling dust removal, causing the dust to float in the air again and affect the dust removal effect. When in use, the user can pull the vehicle body 1 to move, so as to realize dust removal at different positions in the tunnel to ensure the safe use of the coal mine tunnel.

[0031] After the entire structure is used, the side cover of the water tank 404 can be opened to replenish water inside. At the same time, the cover body 303 can be opened regularly to replace the cloth bag, and the flange can be used to contact the exhaust pipe 306 to limit the small amount of water flow inside the exhaust pipe that may be splashed.

[0032] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the concept of the present invention, many changes can be made in the specific implementation method and application scope. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of the present invention.
